The idle is 950rpm it is maybe 75 rpms higher that normal,also I am getting 1189, 1188 codes talk to Active, Craig said that I have a small vacume leak.
Correct me if I am wrong but smoke test will be the most cost efficent way to detect and neutralize the problem, if yes where in north york/ vaughan or mississuga area can I get it gone?

Replaces O2 senser both on banks one and two. got both codes back, Drove with check engine light for 2-3 days, today started the car in the morning the check engine light is gone, connected my OBD reader the codes are still there. WTF?
